I • WETLAND DETERMINATION REPORT Glacier Valley Estates Property Verona, Dane County,Wisconsin INTRODUCTION On February 15, 2006, Applied Ecological Services, Inc. (AES) conducted a Wetland Determination at the Glacier Valley Estates Property in Verona, Wisconsin (Figure 1). Our investigation focused on determining whether wetlands exist in the area "west of the driveway and house" per a site visit letter dated February 9, 2006 by Cami Peterson of the Wisconsin DNR (Appendix 1). The jurisdictional status and boundary of any wetland that was potentially identified on the property is based upon our best professional understanding and interpretation of the Corps of Engineers Wetland Delineation Manual(1987)and Corps guidance, documents, and regulations. The Corps administers Section 404 of the Clean Water Act,which regulates the discharge of fill or dredged material into all "waters of the United States," and is the regulatory authority that must make the final determination as to the jurisdictional status of any wetland in the project area. METHODS Prior to the February 15, 2006 field investigation, we reviewed several resource maps available from County, State, and Federal agencies, to identify the potential for wetlands on the property. These maps included the Wisconsin Wetland Inventory Map (WWI), and the Natural Resources Conservation Service (NRCS) Soil Survey for Dane County. 'I he Corps does not accept the use ()Obese maps to make a final wetland determination, therefore we use this information only to eJtaOliiJh the probability' :71141 approximate location of wetlands on the site. We developed a preliminary site base map, applying property boundary limits to the most recent scaled, ortho-rectified digital air photo coverage available. During our field investigation,we conducted a thorough reconnaissance of the project area, to confirm project boundaries and land cover types, to assess site conditions, and to establish sample point locations that best represented the wetland and upland plant communities. At each sample point location we recorded dominant plant species and their associates, soil characteristics, hydrological characteristics, and other information necessary to complete the USACOE-approved Routine Wetland Determination data forms. The wetland indicator status of all documented plant species was determined using the National List of Plant Species that Occur in Wetlands (Reed 1988). Sample point locations were labeled numerically on the site base map. Sample point locations were photo documented. Applied Ecological Services, Inc. AES Project#06-0156 Page 3
